Taja Boscarol of Pipistrel in Slovenia relays the information that NASA has tested Pipistrel’s electric propulsion system as part of its electric flight research for the X-57 program. It would seem reasonable to start by checking out Pipistrel’s well-tested motor package, one of the few that comes with fully-matched controller, batteries, and ancillary gear. NASA performed its tests on its 13.5-foot Airvolt stand at the Armstrong Flight Research Center at Edwards Air Force Base, California. Heavily instrumented, the Airvolt stand collects data through “high-fidelity sensors,” and transmits the collected information to a data acquisition unit that processes, records, and filters the measurements. NASA and Pipistrel should be able to make good use of this data. Normally installed on the Taurus …
